Two Canon FD lenses - which one is better?

Hi there,

I am looking at a mild wide angle lens (35mm) and saw these two come up.
One is an old SSC breech mount, the other is a "new" FD. The only difference I know is that the two have different fitler threads (the old is 55mm, the new is 52mm). Does anyone know how different these two are, quality wise, etc? I know the old SSC lenses were very good, but I was also told that all the new FD lenses basically had the same standard of optics. I am not sure I believe that...So far, I have a collection of 55mm filters, so if the lenses are identical, I'd hold out for an older SSC - all other things being equal. What do you think?
